The Bandai kit is really a reduced Tamiya in terms of accuracy and detail. It could use some PE for the smaller details, but of course, there isn't any because the Bandai stuff isn't kin production. Nigel Savage at Parabellum UK was able to get Hauler to make up a run of PE for the old Bandai Valentine Mk III tank, as apparently there are a number of them available in the UK. Except for that, there isn't much for any of the Bandai stuff.
Changing out the tracks, thinning the body side panels around the crew entry cutouts, and adding the smaller details would go a long way to perking up this old warhorse. For example, the tool stowage was on the front sides of the seat boxes above the floor, and of course, the Kar 98K rifles all had their brackets on the backs of the seats in front of the seats behind.
I had sonme shots for the SdKfz 6 5-ton tractor at Fort Knox, but I can't find them right now. They showed the tool stowage brackets, and I'd guess the stowage for the SdKfz 7 8-ton tractor was pretty much the same. I'd use the new Dragon 1/35 kit as a reference for the tool stowage, if it has such. No doubt at this point some enterprising soul has written a nice book on the SdKfz 7 (I hope....

) and that will have all the internal tool stowage shown.
It would be nice to have PE for a new windshield frame and the other finer parts, but we'll have to work with scrap strips or styrene strips and .010" clear plastic for the glass. Looking at good photos and 1/35 models can be the best reference you can find. Some existing PE sets for other kits may supply some of the smaller common details you'd need (small chains, locks, etc.).
